<p>Defines the <code>Node</code> abstraction used by <code>dagpipe</code>.</p>
|

<p>A node represents a single unit of pipeline execution logic. It consumes one

<code>State</code> and produces zero, one, or many new <code>State</code> objects.</p>
|
||
<p>Nodes are connected using a <code>Graph</code> and executed by an <code>Engine</code>.</p>
